SPECIFICATION forming part of Letters Patent No. 359,485, dated March 15, 15887.

A pplicntion filed August 25, 1884. Serial No. 141,352. (No model.)

To all ZU7L0772/ it may concern.-

Be it known that L'OsoAn J. ZIEGLER, a resident of Freeport, in the county of Stephenson and State of Illinois, haveinvented certain new and useful-Improvements in WVire-Barbing Machines; and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in wire barbing machines, the novel features thereof being embodied in the machine which is described and explained in this specification and shown in the accon'ipanying drawings, of which Figure 1 is a plan of the entire machine, except thefsprocket-wheels f f of the take-up mechanism; Fig. 2, a front elevation of the machine looking in the direction indicated by the arrow a, Fig. 1; Fig; 8, aside elevation of the machine, looking in the direction indicatedby the arrow a, Fig. 1; Fig. 4, a longitudinal vertical section of the bed of the machine through thelinew y, Fig. 1, showing the device for actuating the take-up mechanism, the view being in the direction indicatedby the arrow at, Fig. 1; Fig. 5, a longitudinal vertical section of the bed through the line 00 1", Fig. 1, looking in the direction indicated by the arrow a, Fig. 1, showing the wrapping-sleeve and its support and the mechanism by which it is moved longitudinally; Fig. 6, abottom plan of the lever which actuates the wrappingsleeve. I

In Fig. l are shown devices for feeding two main wires and one barb-wire and means for cutting the barb-wire. The feeding devices are shown in Fig. 3, but the cutting mechanism is omitted, and in Fig. 2 no feeding or cutting mechanism is shown. In Fig. '2, for the purposeof showing more clearly the segmentactuating mechanism, a portion of the front of the machine is broken away. The part so removed is shown in Fig. l in the angle between the lines 00 y at the'left-hand front corner of the bed of the machine, and is cut away by vertical planespassing through said lines.

In the figures above enumerated, A is the bed of the machine. B is the main shaft, and

B aside shaft at right angles to the main shaft. A pulley, O, rotating in the direction indicated by the arrow on its rim in Fig. 1, is mounted on one end of the main shaft B, and

serves as a means for applying power to the machine, and suitable miter-gears connect the shafts B B and transmit the motion of the main shaft to the side shaft. On the opposite end of the shaft Bfrom the pulley O is mounted a crank-plate, H, which imparts, through a pitman, I, and a pawl-and-ratchet mechanism,

1 F G, intermittent rotation to a pair of double feed-rolls, D D D', Figs. 1, 3, adapted to feed forward two main wires, 0 c, and on the front end of the side shaft, B, is mounted a crankplate, H, which imparts through a pitman, l and pawlandratchet mechanism F G intermittent rotation to a pair of single feedrolls, D D", Figs. 1, 3, adapted to feed a sin gle barb-wire, 0, across the path of the main wires and under and in contact with the wire 0, on which the barb is to be formed.

To prevent the rotation of the feed-rolls D D D' by the tension of the main wires, a ratchet-wheel, F, is rigidly mounted on the shaft B, and a pivoted pawl, \V, Fig. .1, is so placed as to engage the ratchet-wheel during the forward swing of the crank G and pitman I, but is lifted out of such engagement at the commencement of the backward stroke of the crank and pitman by means of a cam, V, mounted on theshaft B.

In front of the barb-wire and between the main wire 0 and the barb-feeding mechanism is a stationary knife, a, Fig. 1, provided with suitable means of longitudinal adj ustment, and in rear of the barb-wire is aknife, a, set in a rocking head, '1, (in which it may be adjusted at pleasure) adapted to co-operate with the stationary knife a and sever the barb-wire immediately after the formation of each barb on the main wire. Motion is imparted to the head T by means of a suitable cam on the main shaft B, and the knives are thus operated once for each rotation of the pulley O and main shaft B. I 1

As the feeding and cutting devices above mentioned are well known in wire-barbing machines and are the same as those shown and described in the patent of Daniel G. Stover,

No. 278,624, I do not think it necessary to explain them in detail here.

The main wire a is supported immediately in rear of the barb-wire by a longitudinallyperforated stationary spindle, 0, through which it passes, the spindle itself being supported by a stationary bearing, It, in which it is rigidly fastened, and the bearing being fixed to the bed by any suitable means. 011 the spindle O, in front of the bearing It, rotates freely asleeve, O, somewhat shorter than the exposed portion of the spindle, and having in its front face an ordinary wrapping-pin, and about its periphery a grooved collar, P, and a pinion, 2, Figs. 1, 2, The pinion 2 engages with agcared segment,M, Figs. 1, 2, formed integrally on the inner end of the vertically-oscillating lever K, which is pivoted on a suitably-supported horizontal shaft, L, parallel to the shaft B. The outer end of the lever K has formed on its front face a boss, K, whose axis is somewhat nearer than the axis of the shaft B to the wrapping-spindle O. The shaft B is bent at a point opposite the lever K to form a double crank, B and the crank so formed is connected with the boss K by apitman, J, Figs. 1, 2, provided at both ends with suitable boxes, which inclose the crank and boss, respectively. It is evident that the rotation of the crank B must impart vertical oscillation to the lever K and segment M, and thus cause reciprocal rotation of the pinion 2 and shell 0.

In the lower half of the annular groove in the collar P rests a yoke or fork formed integrally with a vertical rod, N, Figs. 2, 3, 5,

which extends downward through 2 the bed,

andis adj ustahl y attaeherl to the vertical mem- "tenor, abell-crank :lever, Z. -The-lever Z is pivoted on a horizontal. boss, ,Lif, attachedto the lower face of the bed of the machine, and its horizontal member extends. baekwardfr the pivotal point. to a point somewhat in rear A cam, V, Figs. 1, 5,

rear endof thelever being held in contact with ,:the cam by a spring, m, Fig.6, one end of: which is attached to the lever; and theother; :endtothe lower partof the bearing 11. oscillation ,ofc the leveri impartsreciprocal longitudinal motion to: the sleeve -O-,'and the extent of this motion is such thatwhen the sleeve is at itsiforwlard limit of motionits front face is flush with the front face of the spindle O, and when the sleeve is at its rearward limit the front end of the wrapping-pin is slightly in rear of the front face of the spindlethat is to say, when the sleeve is at its forward limit the wrapping-pin is in position to operate on the barbwvirc; but when the sleeve is at its rearward limit the pin is wholly out of range of the barb-wire, and may rotate as far as desired without liability to strike it. The cam V is so timed as to hold the sleeve at its forward limit of motion (i. 0., in such a position that the wrapping-pin is in working position) during the wrapping and cutting of the barb. As soon as the barb is severed the sleeve recedes, the pin drops back in rear of the front face of the spindle O, the barb is released, and the forward feed of the main wires commences. At the instant after the mainwire feed commences the barb-feeding mechanism begins to operate, and, since the wrapping-pin has been retracted out of range of the barb-wire, the entire barb-feed can be made during the reverse rotation of the sleeve 0. Since the barb is fed below the main wire 0, the wrapping motion of the sleeve 0 must be caused by and be simultaneous with the up ward movement of the segment M. At the close of the upward movement of the segment the sleeve is drawn back, as above described, and during the moment when the segment is at rest at its highest position, and while it is moving downward, the sleeve and its wrapping-pin are out of working position. This is especially important when, as in the machine shown in the drawings. the segment-lever is actuated by a crank and pitinan. The deadpoint of the crank causes a rest of considerable length at the end of each upward or downward stroke of the segment, and renders it impossible to obtain the quick return which is possible when the segment-lever is moved by a cam. On the other hand, the motion imparted to the segment by the crank and pitman is smoother and more satisfactory than that obtained by the use of a cam. It has heretofore been impossible to get satisfactory results from the combination of the crank with the scgmentlever, for the reason "thatiasith e bz'irb-feed could not bemadecuntil after the reverse motion of the wrapping-pin had been nearly completed, the restart the end of the upstroke of the segment wasso long that when added to the downstrokc'of the ment it left an insufficient time for the barbfeed. In other words, thc rests in thenrotion of the segment, caused by the dead-points in the motion ofthe crank, wasted so much of the workingtime of the maehineasto make a sat isfactory speed impossible. The combination of thelongitudinally reciprocating sleeve (or i i an y equivalent means offalternateliy advancing 1 and retractingthe wrapping-pin) withf thes'cg-i I p I ment; segment-lever, and crank; and pitinan removes this objection and makes theworking of the machine extremely rapidas well asex tremeliy smooth.

As the main wire 0 is barbed, it passes forward from the spindle O, is carried over two sprocket-wheels,ff, pivoted on horizontal gudgeons set in the side face of a vertical oscillating post, It, and passes from the lower sprocket wheel backward to a reeling and twisting device beneath the bed ofthe machine, which will be hereinafter explained. The unbarbed main wire 0' passes forward from the feed-rolls D D through a slot, M, in the segment M, and over the sprocket-wheels f f to the reeling and twisting device, by means of which it is intertwisted with the barbed wire end of a pitman, 9, Figs. 1, 2, 3, 4, which extends backward under the bed of the machine to a point slightly in front of the main shaft B. The rear end of the pitman g is hinged or j ointed to the lower end of a dependent swinging lever, U, whose upper end is supported by a pin, L, set in a stationary-support, S, which is bolted to the bed of the machine. A cam,V, mounted on the shaft-B, gives a swinging motion to the lever U, which is held in contact with the cam by a spring, m, Fig. 4c. The forward motion of the lever U thrusts forward the pitman g and swings forward the post It and sprockets f f, and the cam V is so timed that this forward swing of the sprockets begins and ends simultaneously with the forward feed of the main wires, while the return swing of the sprocket-s occupies the time during which the main wires are at rest.

The duration and speed of the oscillation of the post it are such as ,to equalize the movement of the main wires from the barbing mechanism to the reeling device beneath the machine, the forward motion of the sprockets'being such as to take up a portion of the slack caused by the forward feed of the main wires, while the backward movement pays out the slack taken up in the forward movement, and thus supplies the reel with wire during the cessation of the feed.

The reeling and twisting mechanism shown is substantially the same as that in common use with wire-barbing machines, and consists, essentially, of a flier, t, hung in suitable horizontal bearings, a transverse shaft near the center of the flier,on which to mount a spool, a transverse double-cut screw, j, and a distributing sprocket wheel, f", moving thereon, a sprocket-pulley, w, by means of which the flier is turned in its bearings, and gearing for rotating the spool and the shaft on which it is mounted. The flier is provided with the ordinary two-part friction-box, 'v o c o,which is regulated by means of a cord, 1, one end of the cord being fastened to the movable part of the box, while the other end is passed over a pulley, u, and thence to a ratchet-toothed handwheel, 8, provided with a pawl, t. The only novel features claimed for the mechanism are, first, its arrangement under the bed of the machine, by which great economy of space is secured, and, second, the enlargement of the hollow shaft t and bearing 12 to permit the distribution of the barbed wire from the sprocket f directly to the spool without the intervention of a guidewheel in the throat of the hollow shaft. The flier is provided with support by bolting to the legs,'at each end of the machine, a web, Z, with which is formed inte-. grally one-half of the box which receives one of the hollow shafts of the flier, the other half of the box being bolted in place, as shown in Figs. 2, 3. This forms a simple and substantial support for the reeling and twisting mechanism, and is as well adapted for the purpose as any which can be devised; but its form can of course be varied, if desired, so long as the position of the flier remains substantially the same and the proper economy of space is pre served.

It has been customary heretofore to place a small guide-wheel at the inner end of the hollow shaft of the flier, through which the barbed wire enters, and to carry the wire from the guide-wheel to the distributirig-sprocket, and thenceto the spool. When that was done, it was necessary to place the transverse screw j and distributing sprocket f much farther from the inner end of the hollow shaft (and from the end of the flier) than they are shown in the drawings.

In the machine shown the barbed wire, when the distributing-sprocket is farthest from the center, describes a cone, of which the vertex is the point of contact of the wire and the sprocketf, while the screwjis the diameter of its base. \Vhen a guide-wheel was placed in the throat of the hollow shaft, the base of the cone described by the wire remained the same as in the machine shown, but the guide-wheel was the vertex of the cone. The added length given to the cone by taking out the guide wheel and enlarging the hollow shaft 1' permits the screw 9 to be brought almost to the end of the flier and allows the flier to .be materially shortened,thus effecting a considerable saving in space and weight and a consequent gain in smoothness and speed of motion.

I am aware that it is not new in wire-barbing machines to retract the wrapping-pin which forms the barb, in order to take it out of range of the barb-wire, since this feature may be found in a number of machines already patented or in public use. I am further aware that there are many ways of withdrawingthe wrapping-pin from a working position, any one of which would be as practical as the method illustrated and described herein. 1 do not, therefore, desire to limit my invention to the combination of the special means shown for that purpose with the other elements of my machine, since it is evident that in any combination of which these means are an element they may be replaced by other substantially equivalent devices without materially altering the principle of operation of such combination.

All the features of this machine, except the barb-wrapping device, may be used in applying a barb to both the strands of a twostrand cable, as well as for making a cable one of whosestrands is barbed and the other plain. The forming of a barb about both the strands requires the substitution of well-known and obvious barb-forming parts for the sleeve and spindle O O in the exact forms shown, but the combination of the crank and pitman with the segment-lever and means for withdrawing the wrapping-pin out of range of the barb-wire, the tal e-up mechanism, and the improved reeling and twisting device can all be used in the modified machine to the same purpose and with the same advantage as in the machine shown and described.

In making single-strand barbed fencing it is customary to twist the wire as it is reeled sufficiently to set each barb in aplane at right angles to the plane of the barb next to it in either direction, or, in other words, to put into the wire ninety degrees of twist for each barb applied to it. It is evident that the machine shown will make such fencing as well as a two strand cable, the only change necessary being a variation of the speed of rotation of the flier which carries the spool for taking up the fencing.

Having now described my invention and explained its operation, what I claim as new, and desire to secure by Letters Patent, is

1. In a wire-barbing machine, the combination of an intermittent main wire feeding mechanism, a barb-forming mechanism eon strncted and arranged to operate in the intervals between the forward movements of the main wire, a reeling and twisting mechanism in entering which the barbed wire moves in a direction contrary to that of its motion from the feeding to the barbing mechanism, a guide wheel or wheels about which the barbed wire passes in changing the direction of its motion, and from which it passes to the reeling and twisting mechanism. and means for increasing the distance 01' said guide wheel or wheels from the barbing mechanism during each forward movement of the main wires, and decreasing such distance during each interval between such forward movements, substantially as and for the purpose set forth.

2. In a wire-barbing machine, the combination of an intermittent main-wire feed, a barb-forming mechanism constructed and arranged to operate in the intervals of rest of the main-wire feed, a reeling and twisting mechanism suspended beneath the bed of the machine, an oscillating vertical support in front of said machine, a guide wheel or wheels mounted on said. oscillating support, about which the barbed wire is carried in its course from the barbing mechanism to the reeling and twisting mechanism, a pitman connecting said oscillating support with the machine, and means for imparting longitudinal reciprocal motion to said pitman, whereby the support is moved forward during the operation of the main-wire feed and drawn back in the intervals of rest thereof, substantially as and for the purpose set forth.

3. The combination of an intermittent mainwire-feeding mechanism, a barb forming and applying mechanism operating in the inter vals of rest of the main-wire feed, a reeling and twisting mechanism journaled in suitable supports beneath the bed of the machine, the post 71, sprockets ff, mounted thereon, the pitman r swinging support U, and cam V, substantially as shown and described, and for the purpose set forth.

In testimony whereoflhavesigned this specification in the presence of two subscribing witnesses.
